Description of the problem

When in raw mode, input is always available character-by-character, not including modifiers. Additionally, all special processing of characters by the terminal is disabled, including echoing input characters. Ctrl+C will no longer cause a SIGINT when in this mode.

This is wrong. Special processing of newline characters is still done and it is not binary safe.

See libuv/libuv#32 for historical context.

Note that I think this function name is misleading compared to user expectations, and there should be a way to have binary safe I/O (what raw mode normally is).
